Mark Stephens attacked the decision by the Swedish authorities to appeal against a judge’s ruling to grant the 39 year-old Australian bail.
He said their decision was now a “‘persecution” rather than a prosecution and was politically motivated.
He accused the authorities of stopping at nothing to have the Wikileaks founder behind bars, a claim they denied.
“Finally after two hours we have heard the Swedes want to appeal against the bail conditions and put Mr Assange through yet more trouble, more expense and more hurdles,” he told reporters outside City of Westminister Magistrates Court.
“It is really turning into a show trial and we will be in court again within the next 48 hours as soon as we have all the information.”
“It is an unfortunate state of affairs given that we were obviously very relieved for Mr Assange a few hours ago now that the Swedes have taken this position. But given their persecution of Mr Assange perhaps it is not surprising.”
Earlier Stephens praised the celebrities who have backed Mr Assange since his arrest, some of who offered to stump up the £200,000 surety to secure his release.
“We have a number of people who were prepared to stand the surety of £20,000 each,” he said.
“Jemima Khan, Bianca Jagger, John Pilger and Ken Loach, among others, are pillars of the community who have risked their reputation to stand by him [Mr Assange].”
Stephens added Assange was ‘worried’ about his colleagues at Wikileaks but said he understood they had to carry on their work while he was incarcerated.
Assange’s legal team will now take the case to the High Court to secure his release on bail while he continues to await extradition to Sweden.
Stephens said his client “believed in British justice”.
“But there is a problem because he has been granted bail on condition that £200,000 is paid into the court,” he said.
“That is an awful lot of money.”
Stephens said it would take an “inordinate” length of time to get the bail money together.
“Until then we have an innocent man in Dickensian, Victorian conditions in Wandsworth jail,” he said.
“It is impossible to say how long it will take before Julian Assange is out. The problem is £200,000 cannot be put in by cheque as that takes seven days to clear.
“So I have to go around to find cash and have it delivered to court, and until the court has it an innocent man stays in jail.”
Stephens branded the bail conditions “Orwellian” and said he would ask to relax them at a later date.
He warned the extradition process could take “many years” and highlighted the ongoing ordeal of Gary McKinnon, the British computer expert wanted in the US for hacking into military computer systems.
The lawyer said his client could not speak to other prisoners at Wandsworth Prison and was locked up for 23 hours a day.
He added that mail was not getting through and a copy of Time magazine featuring Assange was “ripped up by the censors” and he was only given an empty envelope.
Stephens said author Hanif Kureishi and filmmaker Michael Moore were among the people who offered to give surety on behalf of the WikiLeaks founder.
“These are pillars of the community prepared to stand their reputation behind Julian Assange,” he said. The Telegraph
